JOHN T. NOTE, OF BUFFALO, NEW' YORK.

CLUTCH FOR FLOUR-PACKERS.

Specification of Letters Patent No. 15,145, dated J une 17, 1856.

To all whom t may concern Be it known that I, JOHN T. Noria, of Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Machines for Packing Flour in Barrels, of which t-he following description, illust-rated by the accompanying drawing, is sufficiently clear and comprehensive to enable others of competent skill to make and use my invention.

The nature of my improvement consists in the arrangement herein described for throwing the packer shaft in and out of gear with the driving shaft by means of a triangular self adjusting guard used in connection with a hollow cylindrical chamber and hollow shaft.

Figure l is an elevation of a whole packer with parts of the mill to which it is attached. Fig. 2, is a perspective view of the parts upon which my improvement is made showing one of the arrangements for conneet-ing and disconnecting the packer shaft with the hollow or driving shaft lV. Fig. 3, is an elevation of the parts between the lines w, of Fig. 4, turned around so as to show a side view of the sliding guard e, sometimes used instead of'the triangular guard o. Fig. 4, is a vertical section of my improvement cut through the center showing the construction of the chamber and the connect-ion of the two shafts, &c.

A, Fig. l, are parts of the frame of the mill.

B is the barrel in which the flour is packed standing on a movable bed or platform C, which is raised and lowered by the lever D, and rod F, in the usual manner, being fixed in its place at pleasure by the ratchet upon E and a catch E.

Gr is a conical part of the fiour chest and H, the square portion. The lower or conical portion terminates in a metallic cylinder I, which enters the top of the barrel. Passing through this chest (represented in dotted lines, Fig. 1,) is the packer shaft with the screw packer upon its lower end represented in the same manner. This packer shaft is supported by cross bars within the flour chest H. J, is a coupling in the shaft.

The driving shaft T and cylinder l/V are hung in bearings m3 upon the bracket or, which is bolted to the upright post in the frame A; this cylindrical driving shaft is slotted upon each side as represented at s and these slots terminate at the upper ends in the circular cylindrical chamber K, as shown in section in Fig. l. A pin f is fixed in the packing shaft, each end of which projects from the shaft and fills the slots above named so that the driving shaft by means of this pin will carry the packingl shaft along with it when it revolves, until the packer shaft rises so that the pin may turn in the chamber K.

To prevent the pins from striking the corners formed by the slots and cylindrical chamber (which is found to be a great objection to the use of these packers) either of the methods mentioned below may be used, viz, t-he triangular self adjusting guard or the sliding guard c, This self adjusting guard seen in Figs. 2 and 3 is hung by a pin in the center and is free to turn in either direction. Its natural position will leave the arms w, inclined to the horizon at about forty-five degrees, one of these arms balancing the other. In its natural position one arm extends across the slot in the driving shaft and as the packing shaft rises the pin passing through one of these slots catches the arm ac and turns itaround so that this arm stands nearly vertical, and the upper end of it reaches a little above the base of the hollow cylindrical chamber, so that the pins f are thrown to the upper part of the hollow cylindrical chamber before they can revolve in it. After the pin passes over the top of this arm the arm falls to its natural position by its own weight. After being thrown up to this posit-ion the packing shaft is kept here at pleasure by the rod L, and its attachments in the usual manner. The sliding guard e is used sometimes to accomplish the same purpose, being carried up by friction of the pins upon its sides next t-he slot, and falling by its own weight when the pin passes over it into the cylindrical chamber K. Either of t-hese arrangements accomplish an object. in an easy and convenient manner which has heretofore caused much difliculty in the use of these machines. The gear wheels M, and N, are arranged in the usual manner as shown in drawings.

The upper end of the packer shaft is attached to the cross lever P, Fig. l, which has the rod L upon its opposite end. This rod has a rack upon its lower end working upon a cogged wheel upon the same shaft with the hand wheel 2, and also upon the and balance or slide guards 0 to drive the pins up into the chamber in the manner and for the purpose herein set forth.

In testimony whereof, I have hereunto 15 subscribed my name before two subscribing witnesses.
